Provided is a surface structure having freezing-delaying performance and freezing layer-separating performance The surface structure includes a microstructural layer formed in the form of microscale irregularities and a plurality of nanopores formed in the microstructural layer. A freezing-delaying layer is formed on a surface of the microstructural layer to delay a freezing phenomenon. Also, a hygroscopic material is accommodated in the nanopores, so that when a surface of the freezing-delaying layer starts to freeze, the hygroscopic material is discharged from the nanopores to form a hygroscopic material film, and thus adhesion between the freezing-delaying layer and ice is reduced to allow the ice to be detached from the freezing-delaying layer.
